something between the main amp and the main speakers

to keep the low bass out of the main amp and therefore out of the main speakers.
As a purest, I can't take a line stage crossover in line with the mids and highs but just a high quality cap does wonders.
The filter slope is shallow (only 6db per octave) but it really helps a lot.
I built a 12db per octave Sullen-Key OpAmp based low pass filter to go between the woofer amp and the JBL 2231s (no where near as harmful to low frequencies) but just use one cap per channel as a high pass filter to keep the low bass out of the main amp.
